The pattern shows: three consecutive letters (B,C,D), skip 3 letters (E,F,G is shown), then three consecutive letters (O,P,Q). After G, we skip H,I,J to continue to O, but wait - J is actually needed to bridge G to O. The pattern is B,C,D, then G (skip 2), then J (skip 3: H,I,K), then O,P,Q (skip 3 from J).
